1. Re: Clustering failing under heavy load?
monu Mar 22, 2004 8:40 AM (in response to danhanley)hi,
I am also getting similar issue. I am using jboss-3.2.2.
While starting jboss, our application starts some threads which pull messages from JMS queue and perfrom some business logic on it, Messages are file persistence message, so if Queue has got many message stored and when jboss restarts , our application starts processing those message thats generate load on machine and because of that server doesn't enters in cluster.
Regards,

Hi
We're testing a cluster of 3 intel boxes running jBoss 3.2.3 on RedHat 9.
One box in particular is very heavily loaded by our application. Occasionaly (perhaps once a day) the box stops communicating with the rest of the cluster and fills its logs with the following message:
2004-01-22 09:29:36,458 DEBUG [org.javagroups.MDC3TestPartition] [Thu Jan 22 09:29:36 GMT 2004] [ERROR] UDP.sendUdpMessage()
: (unicast) send_sock is null. Message is [dst: 213.86.178.88:44305, src: dev4:32947 (3 headers), size = 1723 bytes], headers are {UNICAST=[UNICAST: DATA, seqno=47],UDP=UDP:group_addr=MDC3TestPartition], MessageDispatcher=[Header: name=MessageDispatcher, type=RSP, id=1074701665445, rsp_expected=false]}
Stopping and restarting jboss clears the problem, but obviously is not something we want to be doing when we go to production.
Do you have the logs for this ? Also, can you post your cluster-service.xml ? You may have to increase the values for FD, or use FD_SOCK instead.
